I would not go that far to say that requirements never satisfy other requirements, but it is very uncommon.
The relation information you want to model between your requirements is not supported by SysML.
However e.g. , the Goals in the KAOS framework defines a kind of “contribute” relationship which can be rated between -3 …+3. So you could express that fulfilling one requirement contributes a bit (+1) or very much (+3) in fulfilling another requirement. Or you could model that fulfilling one requirements makes it really hard (-3) to fulfill another requirement.
UML and SysML allows you to add something like that by a profil. So if this information is important to you, create your own profile maybe with ratings [impossible, -3, -2, -1, +1, +2, +3, entirely].
